I built one of these based on Matt’s from his video at https://m.youtube.com/watch?v=3pBbKNrkixY
You don’t really need the plans but go ahead, he only wants $5.
If anyone is interested I’ll post some tips on building one.
These are heavy but very stable and useful.
I already had all the materials except the dual sliding track at the top.
Watch the video to see all the functions especially how to easily make taper cuts.
